PATENT OFFIC EGG-PRESERVING.COMPOUND.

SPECIFICATION formingpart of Letters Patent No. 747,372, dated December22, 1903.

Application filed August 21, 1903. Serial No. 170,290. (No specimens.) I

To all whom it may concern:

Be it known that 1, WILLIAM F. BROWN, a. citizen of the UnitedStates,residing at Gold- 'thwaite, in the county of Mills and State ofTexas, have invented certain new and useful Improvements inEgg-Preserving Oompounds; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a compound for preserving eggs.

The invention has for its object to provide a compound which whenapplied to the eggs will form an air-excluding coating adapted topreserve the eggs against deterioration for an indefinite period.

A further object is to provide a preservative coating of this kind whichwill harden the shell of the egg and decrease the liability of the samebeing broken in storage or transit and which is not liable to crack orpeel from the shell.

In carrying my invention into practice I take of clarified gelatin(Ooopers) one-half ounce; Ooxs gelatin, one-half ounce; white gelatin,one ounce, and water (soft) one-half gallon, and thoroughly incorporatethe same together in a suitable vessel. This vessel is placed upon afire and heated until the contents have boiled ten minutes, then takenofi, and when the contents have become cooled the said contents arestrained through coarse toweling. The strained gelatin solution is thencombined with two ounces of waterglass and is then ready for use.

The preservative coating thus prepared may be applied to the eggs bymeans of a brush, but preferably by submerging the eggs therein for asuitable period to secure a complete coating, after which the eggs aretaken out and supported on their points and allowed to drain until thecoating is thoroughly dry. The coating will then harden thereon and fillthe pores of the shell, thus protecting the same from breakage and atthe same time excluding air, so as to protect the egg againstdeterioration for an indefinite period or until the shell is broken andthe contents allowed tobecome affected by the external atmosphere.

My improved preservative coating is readily and easily made, may beproduced at small cost, and is effective for the intended purpose. It issuperior to other coatings of its kind in that the gelatin incorporatedwith the water-glass secures perfect adhesion and prevents the hardenedglass from cracking or chipping from the shell of the egg.

I have found in practice that by using the three kinds of gelatin setforth superior results are obtained, as Coopers and Ooxs gelatin whencombined form a perfect elastic body which is rendered adhesive by theaddition of the ordinary white gelatin.

What I claim is 1. An egg-preservative compound, composed of water-glassand gelatin.

2. An egg-preservative compound, composed of Coopers gelatin, GoXsge1atin,white gelatin, combined with water and reduced to a liquid stateand incorporated with waterglass.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILLIAM F. BROWN.
